Inspired by moths' eyes, scientists have created new technology that may help improve the ...

Because moths need to use every little bit of light available in order to see in the dark, their eyes are highly non-reflective. This quality has been copied in a film that can be applied to solar cells, which helps keep sunlight from being reflecting off of them before it can be utilized. Now, a new moth eye-inspired film may further help solar cells become more efficient.  Read More

The nano-network that releases insulin in response to changes in blood sugar

Aside from the inconvenience of injecting insulin multiple times a day, type 1 diabetics also face health risks if the dosage level isn’t accurate. A new approach developed by US researchers has the potential to overcome both of these problems. The method relies on a network of nanoscale particles that once injected into the body, can maintain normal blood sugar levels for more than a week by releasing insulin when blood-sugar levels rise.  Read More

NC State's self-healing elastic electrical wire

Last month, we heard about how a team led by North Carolina State University’s Dr. Michael Dickey had created an electrical wire that could be stretched up to eight times its regular length ... and still carry a current. This was possible thanks to a conductive liquid metal alloy of gallium and indium, contained inside the wire’s elastic polymer outer housing. Now, Dickey's team has developed a new wire that not only can be stretched, but that will heal itself when severed.  Read More

A microscope image of NC State's nanofiber-studded silicone

For several years now, scientists have been exploring the use of patches of arrayed microneedles as a means of “injecting” medication through the skin. Researchers at North Carolina State University are now working on something similar, but at a much smaller scale – they're developing tiny needle-covered balloons, to deliver medication to individual cells.  Read More

One of NC State's stretchable conductive wires being put to the test

Things like earbud cords have a nasty way of getting hooked on things and breaking. Such incidences may become a lot less common, however, as scientists from North Carolina State University have created conductive wires that stay intact even when stretched up to eight times their regular length.  Read More

NC State researchers say WiFox software can improve data throughput by up to 700 percent (...

Researchers at North Caroline State University have come up with a new tool to speed up public Wi-Fi hotspots. The researchers say that WiFox software can improve data throughput by up to 700 percent and could be packaged as an update to existing networks.  Read More

The ribbon-like material being wound onto a spool, while being sprayed with polymer and st...

When people need a material that’s strong yet lightweight, they usually look to carbon fiber. In the near future, however, they may instead choose to go with composite materials made from stretched carbon nanotubes. These materials could theoretically offer the same strength as carbon fiber at one-tenth the weight, or the same weight at ten times the strength. Researchers from North Carolina State University have recently succeeded in creating such a composite.  Read More

The GeS 'nanoflowers' have petals only 20-30 nanometers thick, and provide a large surface...

Researchers have already turned to the humble sunflower for inspiration to design more efficient Concentrating Solar Power (CSP) plant layouts, and now a team from North Carolina State University has developed a “nanoflower” structure out of germanium sulfide (GeS) that shows great promise for use in energy-storage devices and more efficient solar cells. The secret is the material's ultrathin petals that provide a large surface area in only a small amount of space.  Read More

Scientists from North Carolina State University are working on remotely controlable sensor...

Much to the annoyance of home-owners everywhere, cockroaches are amazingly tough, and they’re able to squeeze into remarkably small spaces. These are some of the same qualities that researchers would like to see in tiny reconnaissance robots that could perform tasks such as searching earthquake-damaged buildings for survivors. Such adaptable, robust mini-robots would be quite challenging to create, however. A team of scientists from North Carolina State University are working on an alternative – sensor-equipped real cockroaches that are remotely controlled by human operators.  Read More

The prototype picoprojector, which incorporates the new polarizing technology (Photo: Imag...

Liquid crystal video projectors could be getting smaller, more energy-efficient, and less expensive. Currently, such devices require polarized light for the projection of images. Unfortunately, conventional LEDs only produce unpolarized light. While an optical filter is typically used to polarize it, the polarization process wastes over 50 percent of the original light, converting it into heat instead of allowing it to pass through. That heat, in turn, must be dissipated using a noisy, power-consuming fan. Now, however, researchers have created a new polarizing system that allows almost 90 percent of the LED light to be converted to usable, polarized light.  Read More
